A constable was killed and four policemen injured in a naxalite attack at a police station in Jashpur district of Chhattisgarh early Monday morning, a senior police official said in Raipur.

"A large number of naxalites attacked the Arra police outpost in the district, killing one constable and injuring four policemen, before escaping with some weapons," Director General of Police Om Prakash Rathor told PTI.

The constable died on the spot and the injured policemen were rushed to the district headquarters, Jashpur Nagar, about 400 kms from Raipur, Rathor said.

The naxals also blew up the communication tower, cutting off the link between Jashpur district, which borders Jharkhand, and other areas, he said.

"I have talked to the DGP, Jharkhand as the naxalites might have come from Simdegah and Gumla districts to carry out the attack in Chhattisgarh. A joint combing operation is being planned," he added.

Senior police officials have rushed to the spot and efforts were being made to restore the communication link, the DGP said.
